could you explain me how did you imagine that? i think Glest engine currently not supports FPS style gameplay...
the glest engine supports rts as far as my knowlede of it expands, so i am using a defferent game engine, the darkplaces engine, which is a free modified quake engine.
also i thought if the weapons of key magic and tech units could be instituted
for tech
bow
sword
chainsaw(from battle machiene)
